Sorry, but Red Hat does not support custom kernel builds. For the
- We are unable to effectively QA the infinite set of permutations and
combinations of every kernel option. Consequently, it is impossible
for support to differentiate the implications of every option.
- There are a large set of 3rd party layered applications which have
dependencies on RH kernel versions.
- We produce periodic security errata, etc, which could then be
conflicting with custom builds.
